According to the Los Angeles County Sheriff’s Office, seven black teens have been arrested for their parts in the attack off a 15-year-old Hispanic boy.

Video of the attack, which occurred outside Cactus Middle School in Palmdale, California as the victim was walking home from school, was recorded and reportedly put on YouTube, though it has since been removed.

The video shows that the group approached the victim and challenged him to a fight. Before he could run away, the group began the beating while others stood by and watched.

As the boy was beaten by as many as 10 young males, many shouted derogatory statements and racial slurs. The boy eventually fell to the ground where the assault continued.

In the end, the attack left the victim with bruises, head trauma, missing teeth, shoe prints all over his body. The attack eventually ended because the boy managed to get up and run away.

Authorities say they are investigating the March 14 attack as a hate crime, and the arrested males range in age from 13-16, and have been arrested on charges of assault and committing a hate crime. Authorities continue to look for information on the other suspects and ask anyone with information to come forward.
